Spatial metrics in fire ecology: seeking consistency amidst complexity
Biological Reviews, EarlyView.ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Life, 2021 There are two types of rogue planets, sub-brown dwarfs and “rocky” rogue planets. Sub-brown dwarfs are unlikely to be habitable or even host life, but rocky rogue planets may have a liquid ocean under a thick atmosphere or an ice layer.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora
Biological Reviews, EarlyView.ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Water Evolution and Inventories of Super-Earths Orbiting Late M Dwarfs
The Astrophysical JournalSuper-Earths orbiting M dwarf stars may be the most common habitable planets in the Universe. However, their habitability is threatened by intense irradiation from their host stars, which drives the escape of water to space and can lead to surface ...

Biological Reviews, EarlyView.ABSTRACT The rapid global expansion of photovoltaic (PV) solar facilities, now comprising nearly 80% of the recent and projected growth of renewable electricity, represents one of the most significant land‐use changes of the 21st century. While PV facilities are critical for decarbonising energy systems, their large spatial footprint and infrastructure

Eccentricity formation and habitable planets in OGLE-06-109L system
EPJ Web of Conferences, 2011 Recent observation of microlensing technique reveals two giant planets at 2.3 AU and 4.6 AU around the star OGLE-06-109L. We investigate the eccentricity formation of these two planets, and find that planetary scattering or resonance crossing may be the ...

Transit surveys for Earths in the habitable zones of white dwarfs
, 2011 To date the search for habitable Earth-like planets has primarily focused on nuclear burning stars. I propose that this search should be expanded to cool white dwarf stars that have expended their nuclear fuel. I define the continuously habitable zone of

Symbolic or Substantive Action: Intent, Effort, and Results
Business Strategy and the Environment, EarlyView.ABSTRACT Many firms have made ambitious climate pledges since the Paris Agreement of 2015. These pledges may be symbolic or substantive, but the literature is fragmented in defining these two terms. We propose a conceptual framework with three frames to delineate symbolic from substantive action: Intent—underlying motivations for engaging in climate ...

Habitable Snowballs: Temperate Land Conditions, Liquid Water, and Implications for CO$_2$ Weathering
, 2019 Habitable planets are commonly imagined to be temperate planets like Earth, with areas of open ocean and warm land. In contrast, planets in snowball states, where oceans are entirely ice-covered, are believed to be inhospitable.
